--------------------------------------
Summary: MP REST client causes classloader leak on undeploy
Key: WFLY-13595
URL: https://issues.redhat.com/browse/WFLY-13595
Project: WildFly
Issue Type: Bug
Components: MP REST Client
Affects Versions: 20.0.0.Final
Reporter: Richard DiCroce
Assignee: Alessio Soldano
I have an application that uses CDI and JAX-RS but not MP REST. The MP subsystems
aren't even part of the WildFly configuration. Nonetheless, the MP REST client is
added to the deployment and creates a classloader leak when the application is
undeployed.
See below for the paths to GC root, as determined using a heap dump analyzed by Eclipse
MAT. In particular, note that org.jboss.resteasy.microprofile.client.RestClientExtension
keeps a static reference to the CDI BeanManager.
Workaround: add an exclusion in jboss-deployment-structure.xml to prevent the
org.jboss.resteasy.resteasy-client-microprofile module from being added to the
deployment.
